With the available instruments, the technical knowledge acquired during his academic or apprenticeship programme, the Nose will compose a formula following a precise methodology.
He must use raw materials as an artist uses his colour palette, exploiting maximum effects and taking into account their interaction in order to give life not only to a unique but also physically stable creation using his chemical training. With another challenge: that of anticipating the olfactory result in his imagination during the initial phase of writing the formula down on paper. Just like a musician...
From a purely technical viewpoint, a composition is an assembly of a succession of complimentary raw materials.
Every accord of raw materials from the same family constitutes an olfactory facet (see Section “Instruments of creation”) with specific physical characteristics, which through evaporation with different volatile rates constitute the theoretical structure of the fragrance or “pyramid”, divided in 3 development phases: top note, middle note (or heart) and bottom note (or dry down).
